After trying to play a Song from a T.V. Series, the song is called "Inner Light" and a very short while into the song, you go into the second octave to the highest notes. The problem I'm having is that i Am finding it highly difficult to Pressure or over blow to get to the highest note and the note that is just below it (the note second octave note when you cover none of the holes), especially that second to last highest note.

let's see, on that chart you gave me, i am having problems with going up to third octave D to C#, and keep the C# and third octave D because i accidently go to the lower octave of those notes especially C# and third octave D.

I also mess up in the Switch from C# to B back to C# and continue that second Octave when what i keep doing is going back down to the first octave._________________Jesse E. Coyle

Hmm... I must to check this chart - maybe it's to hard to play it on whistle. When I first time learned this song I did it by ears (I wrote sheet notes in my notebook step by step playing along with mp3 of 'Inner Light' orchestral version on my whistle). At now I'm going to Flickr and check it ;D If it will possible I make trascription for whistle, please be patient

truth be told, i actually found it hard to learn your sheet music... it was confusing... but now i understand that it was the Orchestral version, and thats why there were so many rests. but still i took it on myself to learn by ear of the original (the one plaid at the last 45 seconds of the TV series Episode)

and thats how I came across the third octave D and C# and found it to be difficult_________________Jesse E. Coyle

You can play 2D note like this mouth piece from this side ->: xxxxxx or oxxxxx (x - covered hole, o - open hole). You can read about third octave here -> http://www.rogermillington.com/siamsa/brosteve/ask.html
Don't give up, I made transcription of 'Inner Light' - still high notes but no 3C#.
